Introduction to the GE IC693PWR330 Power Supply
The GE IC693PWR330 is a high-capacity power supply module designed for the Series 90-30 PLC platform. This unit delivers robust power distribution with a total load capacity of 30 Watts. Engineers appreciate its ability to allocate full capacity to the +5 VDC output, making it ideal for larger rack configurations demanding higher current. The module accepts both AC and DC inputs, supporting 100 to 240 VAC or 125 VDC nominal voltages.
Technical Specifications and Output Capabilities
This power supply provides three distinct outputs: +5 VDC, +24 VDC Relay, and +24 VDC Isolated. Each output has a maximum power rating: 30 Watts for +5 VDC, 20 Watts for +24 VDC Isolated, and 15 Watts for +24 VDC Relay. The combined load must not exceed 30 Watts. The module delivers stable output voltages: +5 VDC ranges from 5.0 to 5.2 VDC, relay +24 VDC from 24 to 28 VDC, and isolated +24 VDC from 21.5 to 28 VDC.
Output Voltage and Power Distribution
For applications requiring higher +5 VDC current, the IC693PWR330 permits full 30 Watt allocation to that rail. This flexibility supports power-hungry modules in large 90-30 racks. The isolated +24 VDC output can also provide external power to 24 VDC input cards. The relay output powers electronic circuitry on output relay modules. Engineers must verify total load to prevent overloading.
Installation and Connectivity
Install the IC693PWR330 only in the leftmost slot of the rack. It connects to the backplane to power attached modules. The module features six terminals on its front face for user wiring. For AC connections, use the top three terminals for hot, neutral, and ground (L1, L2, and ground for 240 VAC). For DC connections, use the top two terminals with polarity sensitivity. An embedded RS485 communication port enables connectivity to a workstation, handheld programmer, or other serial devices.
Protective Features and Compliance
The IC693PWR330 includes overvoltage and overcurrent protection for the +5 VDC output, with limits set at 6.4 to 7 Volts and 7 Amps respectively. It provides a minimum holdup time of 20 milliseconds, ensuring stable operation during brief interruptions. The module holds CE and UL certifications, meeting industrial safety standards. LED indicators for PWR, OK, RUN, and BATT status simplify monitoring and troubleshooting.
This power supply remains a reliable choice for Series 90-30 systems, offering essential power distribution and serial communication in a single unit. Its flexible output configuration and robust protection make it suitable for demanding automation environments.
